COMBINED CALIBER AND DIVIDER.

Application filed January 18, 1927. Serial No. 161,862.

It is within the province of the disclosure,

to improve generally and to enhance the util ity of devices of that typeto which the invention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings Figure 1 shows in elevation a device constructed inaccordance with the invention Figure 2 is an end view showingone ot thepoints extended laterally with respect to the arm;

Figure 3 is a section taken through the means whereby the points areheld in ad justed positions.

The device forming the subject matter of this application includes apair of calipers comprising arms 1 which are connected by a pivotelement 2, the arms 1 having cylindrical ends 3 whereon are threadednuts 4:, the nuts 4 having threaded bores 5 for the reception of theends 3 of the arms 1. Slots 6are formed in the ends 3 of the arms 1 andin the srots 6 are mounted the wider ends of points 7, pivot elements 8being mounted in the parts 3 and holding the points 7 in the slots 6 forswinging adjustment in a fixed plane. The points 7 have lateral edges 9and an end edge 10 therebetween, the edges 9 and 10 cooperating to formcorner angles 11. The longitudinal edges which determine the acuminationof the points 7, are designated by the numeral 12.

The points 7 may be alined with the arms 1, as shown at 1 1. the nuts 4being advanced to bear upon the end edges 10, thereby to hold the pointsin the positions stated. When the points 7 are arranged as shown at 1 1,the tool may be used as an ordinary pair of compasses or dividers. Thepoints 7 may be made to extend inwardly, as shown at 15, or outwardly,as at 16, the nuts 1 bearing on the edges 9 to hold thepoints in thepositions stated. When the points are located as shown at 15, the toolis adapted to be used as a pair of outside calipers, whereas, when thepoints are located as shown at 16, the tool may be used as a. pair ofinside calipers. Not only may the points 7 be arranged in the threepositions shown at 14, 15, and 16, but, also, they may be made to assumetwo other intermediate positions, by engaging the angles 11 in the bores5 of the nuts 1, as

shown in Figure 3. Each point 7 has fivecost of a ball and socketconstruction is thereby avoided. The edges 9 are disposed at an obtuseangle with respect to the end edge 10 and with respect to the edges 12.The edges 9 are not located at right angles to the edge 10, and,therefore. when the end of the nut 4 engages either of the edges 9, asshown in Figure 1 of the drawings, the point 7 does not stand at rightangles to the arm 1, but stands at an obtuse angle thereto, this detailfacilitating the operation of the tool when it is used as a pair ofcalipers.

\Vhat is claimed is A. pair of calipers comprising pivotally connectedarms, and points pivoted to the free ends of the arms respectively, eachpoint having similar, angularly-related end edges, said edges definingcornerangles. and a nut threaded on each arm, each adapted to bear atits end upon one of said edges to hold its respective point in adjustedposition, the nuts having threaded bores for the reception of the arms,and the corner angles being receivable in the bores of the nuts therebyto hold the points in still other adjusted positions.

In testimony that I claim the foregoing as my own, I have hereto afixedmy signature.
